Dear All,

Below is an announcement of a lecture on Monday 
the 10th of November 2014 at Loughborough 
University, organised by the ICE East Midlands 
Geotechnical Group (EMGG) and the International Geosynthetics Society (IGS):

Date :Monday 10th November 2014, 6.00 for 6.30pm

Subject : Performance of geosynthetic lining 
systems on landfills: site instrumentation, 
measurements and numerical modelling analyses

Venue: Room RT037, Sir Frank Gibb Building (Civil 
Engineering Building) Loughborough University. 
Loughborough LE11 3TU (Map shown at the following 
link : http://www.lboro.ac.uk/about/findus.html ).

Light refreshments will be available from 6.00 pm.

Speaker : Katarzyna Zamara, FCC Environment

Abstract :

Landfill barriers often comprise a combination of 
geosynthetics and mineral layers. Even though 
well established design methods are applied 
during landfill design process, a lack of data to 
validate and calibrate those approaches is apparent.

The presentation will describe a full scale 
landfill side slope and capping monitoring 
projects, along with collected data, comparison 
with numerical modelling results and drawn 
conclusions. The presentation will describe a 
research study and a current commercial monitoring project.

Instrumentation has been installed on landfill 
sites to monitor geosynthetic lining system 
mechanical performance (landfill side wall and 
cap) and hydraulic performance (landfill cap). 
The sidewall lining system comprising a compacted 
clay layer overlaid by high density polyethylene 
geomembrane, geotextile and sand was monitored 
throughout a period of three years for mechanical 
performance. Data recorded on the site includes: 
geosynthetic displacements (extensometers), 
strains (fibre optics, Demec strain gauges, 
extensometers) and stresses imposed on the liner 
(pressure cells). Additionally, mechanical 
performance of a capping system was monitored 
during capping installation process. 
Instrumentation comprising extensometers and 
Demec gauges was installed on the site.

Further hydraulic performance of three different 
geosynthetic drainage layers installed on a 
landfill capping was monitored. Instrumentation 
comprised standpipe piezometers, volumetric water 
content sensors, run off gauge and geocomposites outflow measurement systems.

Speaker's Biography :

Kasia is a Geotechnical Engineer employed by FCC 
Environment Ltd – one of the largest landfill 
operators in the UK. She is responsible for 
geotechnical aspects of landfill designs, this 
often includes designing with geosynthetics.

She was awarded a Doctor of Engineering for her 
work on geosynthetics in situ performance. The 
project was sponsored by Golder Associates (UK) 
Ltd, EPSRC and CICE at Loughborough University.

Kind regards,

Ashraf
